Description

The present invention relates to a process for reducing the surface energy of organic materials which comprises treating the organic material with at least a S-perfluoroalkyl substituted hydroxybenzylthioether and derivative thereof; to new S-perfluoroalkyl substituted hydroxybenzylthioethers and derivatives thereof; and to compositions comprising an organic material, for example a synthetic polymer, which is susceptible to oxidative, thermal or light-induced degradation and the new S-perfluoroalkyl substituted hydroxybenzylthioethers and derivatives thereof.
The use of various fluorochemical compositions on fibers and fibrous substrates, such as for example textiles, carpets, paper, leather and non-woven webs to impart oil and water repellency is known for example in U.S. 6,127,485 . This reference discloses hydrophobic and oleophobic fibers, films and molded articles comprising synthetic organic polymer wherein dispersed within the fiber, fabric or molded article and present at the surface of the fiber, fabric or molded article are fluorochemical compounds.
The known fluorochemicals do not satisfy in every respect the high requirements which a melt additive is required to meet as reducers of surface energy for organic materials, for example, for increasing the oil and water repellency of organic materials.
It has now been found that S-perfluoroalkyl substituted hydroxybenzylthioethers are useful for various technical applications such as for example for increasing the oil and water repellency of organic materials like for example synthetic polymers. It has also now been found that S-perfluoroalkyl substituted hydroxybenzylthioethers are useful for various technical applications such as for example the making of improved electret articles. In general, a electret is defined as a dielectric material, which exhibits an external electric field in the absence of an applied field [see also G.M. Sessler in Electrets; Sessler, G.M., Ed.; Laplacian Press: Morgan Hill, California, 1998; Vol. 1, Chapter 1].
The present invention therefore provides a process for reducing the surface energy of organic materials which comprises treating the organic material with at least a compound of the formula I

Example 11: Water and oil repellency in polypropylene.

In order to determine the repellency properties of the compounds of the formula I, they are tested according to the following procedure. The sample preparation is a combination of polypropylene nonwovens and a thermal treatment (e.g. 130°C for 10 minutes), which increases the migration of the additive to the surface and a proper surface rearrangement of the chemical groups. This extra heat cycle is recommended to melt the compounds of the formula I in order to obtain a homogeneous redistribution over the surface of the substrate. An industrial sample of polypropylene nonwoven, fabric weight: 40 g/m², is dipped into a 1% isopropanol solution of the test compound, simultaneously applying ultrasonic energy for one minute. After that, the sample is dried overnight at room temperature and then two hours at 90°C in an oven. A part of the sample is afterwards annealed for 10 minutes at 130°C.
The treated nonwoven samples are evaluated in the water repellency test similar to INDA test method 80.8 (99). The wetting behavior of the nonwovens is tested with a series of water/isopropanol mixtures. The observation of the wetting behavior is rated from 0 (water wetting, no repellency) to 10 (optimum water repellency). The results are summarized in Table 2.

The treated nonwoven samples are evaluated in the oil repellency test similar to AATCC test method 118-1997 / ISO 14419. This test follows the same concepts of the already described for water repellency test method, but using, as test solvents, a series of hydrocarbons. The observation of the wetting behavior is rated from 0 (no repellency) to 8 (optimum repellency). The results are summarized in Table 3.

Example 12: Water and oil repellency in polypropylene nonwoven fibers.

Compounding: Samples of the compounds of formula I are heated in an oven at 70°C until they are completely liquefied. The liquid is added at 10-20 ml/min to a twin-screw extrusion of polypropylene pellets via a heated graduated cylinder using a Leistritz MIC 27/GL-32D twin-screw extruder. The extruder zones are 150°-195°C with the main screw at 500 RPM and the PP feeder at 200-250 RPM. The molten polymer and additive exit via a two orifice round die. The molten material is immediately cooled and solidified in a cold-water trough. The solidified strand is fed into a Conair/Jetro 304 Pelletizer. The polypropylene used for the spunbond processing is PP 3155 from ExxonMobil (melt flow rate 36 g/10 min) and PP 3546 from ExxonMobil (melt flow rate 1200 g/10 min) for the meltblown processing.
Alternatively, the compounds of formula I are made into masterbatches by those skilled in the technique. The masterbatch at the desired level is then tumble mixed with the appropriate polypropylene for making spunbond and meltblown nonwovens.
Tumble Mixing: The concentrate pellets are let down with additional polypropylene pellets and are mixed with a Marion SPS 1224 mixer, resulting in a desired additive concentration by weight.
Meltblown Process: Meltblown polypropylene fabrics are prepared from the tumble-mixed additives pellets prepared as above using a custum-bilt 6-inch Melt Blowing Pilot Line under the following conditions: Extruder temperature of 175-240°C. Die and air temperature of 240°C. Throughput 0.479g/h/m (22 kg/hour/meter). Collector belt speed is adjusted to produce a nonwoven with a basis weight of 40-45gsm.

The produced nonwoven samples are evaluated on their water/alcohol repellency behaviour similar to INDA standards (International Nonwoven and Disposables Association) and their oil repellency behaviour similar to AATCC standards. The results are summarized in Tables 4 and 5.

Example 13: Extrusion of TPO tapes (thermoplastic olefin elastomer grade for roofing membranes).

In order to evaluate the surface properties of the new compounds of the formula I as surface modifier, the following procedure is used: TPO is dried in a vacuum oven for eight hours at 60°C. The compound of the formula I is added in an amount as indicated in Table 6 to the dried TPO. The formulations are mixed in a turbo mixer and extruded in a twin-screw extruder (MiniLab extruder from Thermo Fischer Scientific) equipped with a flat die. In this way, TPO tapes are produced with a width of 5 mm and a thickness of around 0.5 mm. The processing temperature is around 195°C. All produced tapes have a beige appearance.
The contact angle of the produced tapes are measured with a Dataphysics OCA 30 contact angle device, using the sessile drop method and water as measuring liquid. The bigger the contact angle, the better. The results are summarized in Table 6. Table 6:
